This invention relates to a ring traveler for ring spinning and twisting, and has for its object to provide a traveler which will I adjust itself to the different relative positions just itself to difierent vamouspositions.

v A further object of the invention is the provision of 'a traveler which will efiectively istribute lubricant between itself and the ring without scraping the lubricant-from the ring and thereby minimize the friction and rmit the same to be operated at a relatively ghrate of s eed. g A. still furt er object of the invention is the provision of a traveler which may be used for difi'erent sizes of yarns or operations at difl'erent speeds, thereb obviatin the necessity of, such frequent changiriifg 0 sizes or weights of travelers for these di erent condiration. With t ese and other objects and advantageous features in view, the invention consists of a novel arrangement of parts more fully disclosed in the detailed description following in conjunction with the accompanying rawings, and more particularly set forth in the appended claims.

I vIn the drawings:

Figs. 4, 5 and 6 are sectional views through the ring showing the relative positions of the traveler, the ring and the yarn respectively at the top position of the rail, the intermedi ate position of the rail and the bottom position of the rail along the spindle;

I Fig. 7 is a section through the center of the shan In ring twisting today high speed is an important and desired object to be obtained,

thus producing tremendous wear upon travelers and rings used in spinning and twisting. To'minimize this wear, lubricant has been resorted to, and it is of importance to obtain a traveler which will distribute the lubricant about the ring to such an extent as to minimize friction thereof and yet without throwing or sputtering the lubricant onto the yarn or work. It is also, desirable to provide a traveler which in itself has the minimum amount of friction on the ring by reason of the she.

thereof; and the followmgis a detailed escription ofthe present embodiment of this invention which will accomplish these results.

With reference to the drawings, 10 designates a spindle u' on which a yarn package 11 is mounted an rotated-by means of a pulley 12 and belt 13. The yarn is drawn from thedraft rolls 14, 15 and 16 through a guide eye 17, to the traveler.18 operating u on the' ring 19 and then to the package 11. T e traveler 18 moves about the rin 19 as the ring 19 is oscillated up and down hy means of the rail 20 upon which it is mounted, whereby to. lay the yarn on the package 11 in the distributed manner desired.

The traveler 18 consists of a shank portion 21 which is'formed on the arc of a single cirdo and at either end of this shank portion 21 there is a hook portion 22 at the lower edge and at 23 at the upper edge for embracing the lower edge 24 and upper edge 25 of the ring respectively. By forming the traveler upon the arc of a single circle, as illustrated in Figure 2 and curving the same in cross section, as shown in Fig. 7, the traveler will contact with the inner surface 26 of the ring at substantially a single point, and I have located this point of contact midway between the opposite edges 24: and 25 of the ring, whereby a true center bearin point is ob tained. By having a center caring .point thus located, the traveler may rock about this point to adjust itself to the varying positions of the yarn.

In Figure 4, the yarn is shown with the rail 20 at its uppermost position of travel at which ballooning of the yarn 27 will be at its minimum, thus a sharper angle will be produced about the upper hook edge 23 of the traveler.

In Figure 5, I have illustrated the rail as about intermediate the opposite ends of its traverse, substantially in the position illustrated in Figure 1, in which the ballooning is greater than in Figure 4, and in which position the traveler is rocked slightly about its point of contact 28 still maintained in the center and assumes the position as substantially illustrated in Figure 5.

In Figure 6, I have illustrated the rail 20 at its lower osition at which the maximum balloonin o the yarn takes place due to its extended ength between the traveler and the guide eye 17 and in which the yarn will ride out nearer the end of the hook, as illustrated in Figure 6, and consequently the traveler will be tilted about its center bearing point, as illustrated in this figure and still maintain its point of contact at substantially the center of the ring. In this manner I reduce the friction between the traveler and the ring and by permitting the ring to adjust itself to the difierent balloonin s of the yarn by having its center point of caring, I prevent the traveler from canting or tipping with reference to the axis of the ring to ]am thereon. The section will show the inner surface of the traveler designated-29 as being slightly rounded so that any sli ht canting or tip-' ping thereof will prevent inding.

I have found by the use of this ring traveler that its friction is so reduced that it will be less necessary to place a lighter or heavier traveler upon the ring for different sizes of yarns on-high speed work due to the fact that the drag or friction is so minimized as to make such change unnecessa tions, said shank being curved on the arc of a single circle extending from one hook portion to the other.

3. A ring traveler comprising opposite hook portions to embrace the opposite edges of a rin and a shank connecting said portions, said shank being curved on the arc of a single circle extending from one hook portion to the other, and located to provide its point of contact with the inner surface of the ring mid-way between its points of engagement with the ed es of the ring.

4. A ring trave er comprising a shank portion convexedly curved on its inner ring engaging surface on the arc of a single relatively large circle and reversely curved to form hooks at either end to embrace the edge portions of the ring and contact therewith and arrange to dispose the innermost surface of the shank in a. plane mid-way between the ring edge contacting portions of said hooks.

In testimony whereof I affix m si ature.

It is of course, understood that the varying positions in Figures 4, 5 and 6 which I have referred to with reference to the position of the rails are also representative to a large extent where a variation in speeds of the spindles is used as of course different amounts of ballooning take place at different speeds, all of which is compensated for by the traveler adjusting itself to the varying conditions.

While I have described certain construction forms which embody the principles of my invention, it is obvious that other desired changes in arrangement may be made with in the spirit and the scope of the invention as defined in the appended claims.

I claim:

1. A ring traveler comprising a head pori tion and a foot portion to embrace the opposite edges of a ring and a shank connecting said portions, said shank being curved on the arc of a single circle, the center of which is in a plane passing substantially midway between the head and foot portions.

2. A. ring traveler comprising opposite hook portions to embrace the opposite edges of a ring and a shank connecting said por-
